1958 Imperial Crown Tires

The 1958 Imperial Crown uses a 950-14 tire size. This is a numeric bias-ply fitment mounted on a 14-inch rim, and it is the primary size associated with the covered Crown application.

That means the first priority is not comparing multiple primary sizes, but making sure the car still has the proper 14-inch wheels and the wheel width is appropriate for the tire being considered. On a collector car, it is also smart to confirm that past wheel changes, suspension work, or long-term storage have not altered the fitment situation.

The 1958 Imperial Crown uses a 14-inch rim with its 950-14 tire fitment. Available tires in this size are built for that rim diameter, so wheel diameter needs to match before any tire is selected.

Rim diameter is only part of the fitment picture on a large 1950s luxury car. Wheel width still matters, especially when comparing available 950-14 products, and the wheel itself should be inspected for age, damage, or previous modifications. A tire can be the correct size on paper and still require a closer check if the wheels are not stock-type dimensions.

Yes. The 1958 Imperial Crown V8 LY1-M uses the same 950-14 bias-ply tire size as the core Crown fitment. There is no separate primary size for that covered sub-model.

That simplifies size selection, but it does not remove the need to verify the actual wheel setup on the individual car. A restoration that retained original-type wheels may only need a sidewall appearance decision, while a car that has seen wheel replacement or suspension changes should still be checked for rim width, clearance, and overall compatibility before mounting new tires.

Start with the correct 950-14 size, bias-ply construction, and 14-inch rim compatibility. For this Imperial, the biggest visible choice is sidewall style, since available options include both narrow whitewall and wide whitewall versions within the same Silvertown Classic Bias Ply series.

After size and construction are settled, compare the wheel-width specification, load figure, and the visual character you want the car to have. A large luxury car from this era depends heavily on tire proportion and sidewall presentation for its stance. Buyers who want a stronger late-1950s visual statement often focus on whitewall width, while road-use planning should also include wheel condition and tire age.

The available 950-14 tires for a 1958 Imperial Crown include narrow whitewall and wide whitewall sidewall styles. Both are bias-ply BFGoodrich Silvertown Classic Bias Ply tires, so the main difference is visual presentation rather than a change in size or overall tire type.

That choice matters on a car with as much side profile as an Imperial Crown. A narrow whitewall gives a more restrained traditional look, while a wide whitewall creates a stronger late-1950s luxury appearance. Appearance should be balanced with fitment basics, so it still makes sense to confirm wheel condition and width before choosing strictly by style.

The available 950-14 options for the 1958 Imperial Crown share the same basic size, bias-ply construction, tire series, and load specification. The main point of comparison is sidewall treatment, with one version using a narrow whitewall and another using a wide whitewall.

That makes this less of a performance comparison and more of a fitment-and-appearance decision. Consider how the car is being finished, whether the goal is a restrained restoration look or a more formal whitewall presentation, and whether the wheel width falls within the tire’s intended range. On a collector Imperial, visual proportion often carries as much weight as the raw specification.

A 950-14 bias-ply tire is the right period-style starting point for a 1958 Imperial Crown because it preserves the vintage sizing format and traditional construction associated with the car’s era. Within that size, the choice comes down largely to the whitewall presentation you want on the finished car.

A restoration-minded owner should think about the car’s overall visual theme, not just the sidewall by itself. Whitewall width changes the look of a full-size luxury car significantly. When exact originality matters, marque-specific references, period photography, and restoration documentation are worth reviewing so the final tire presentation matches the standard being pursued.

Yes, correct tire fitment matters a great deal on a 1958 Imperial Crown restoration. The 950-14 size influences the car’s visual proportion, wheel opening balance, and the formal road-going stance that helps define a late-1950s Imperial.

Construction and sidewall treatment matter too, because an oversized modern substitute or the wrong visual style can change the car’s character even if it physically mounts to the wheel. Keeping the proper size as the foundation makes it easier to choose a narrow or wide whitewall presentation that supports the restoration goal without drifting away from a period-style appearance.

Yes. Even though the 1958 Imperial Crown’s primary size is 950-14, modifications can change whether that fitment still works as expected. Aftermarket wheels, altered wheel width, suspension work, or body changes can all affect how a vintage-size tire sits and clears.

A car that has been lowered, rebuilt, or updated over the years should be checked at the wheel and fender level before new tires are mounted. Steering clearance, suspension travel, and actual wheel dimensions all matter. On an older luxury car, the safest approach is to verify the current setup rather than assume every Imperial still carries its original wheel package.

Before driving a 1958 Imperial Crown on new tires, inspect the wheels, valve stems, lug hardware, and overall clearance at the fenders and suspension. Tire pressure should be set correctly for the application, and the car should be checked for any signs that wheel alignment or suspension condition could affect tire wear.

A long-stored collector car also deserves a broader roadworthiness check. Look for cracked rubber components, weak shocks, brake concerns, and steering play that could make a fresh set of tires feel unsettled. New tires cannot compensate for worn chassis parts, and a large, heavy 1950s car benefits from a careful inspection before regular road use resumes.

950-14 tires on a collector 1958 Imperial Crown should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition. Sidewalls and tread should be examined for cracking, cuts, bulges, irregular wear, and slow air loss, especially if the car is driven only occasionally.

Storage conditions matter almost as much as mileage on a low-use Imperial. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber over time. Moving the car occasionally, maintaining proper inflation, and inspecting the tires before longer drives can help catch problems early on a vehicle that may spend long periods parked.
